DUMPING=CAR.

SPECiPICATION forming part of Letters Patent N 0. 393,009, dated November 20,1888.

A pplication filed July 23, 1888.

To all whom it may concern.-

Be it known that I, WALTER HEATHOOOK, a citizen of the United States, residing at West Point, in the county of Clay and State of use in laying and ballasting railway-track in which the earth, &c., can be uniformly and evenly discharged. My improved car can also be adapted for transporting coal and other commodities, and it is so constructed that the load can be discharged with facility and the carrying-receptacles returned to their normal position without the exercise of any considerable labor on the part of the attendants.

My invention contemplates the use of two movable receptacles mounted on a common carrying frame or body and arranged to discharge their contents at a common point, in combination with independent devices connected with said receptacles and operated from a common motor or source of power to simultaneously tilt said receptacles and cause the contents thereof to be discharged by gravity.

In the accompanying drawings, Figure 1 is a side elevation of a dumping-car embodying myinvention, showing the tilting receptacles arranged in position for carrying the load, and Fig. 2 is a vertical longitudinal sectional view through the car, with the receptacles tilted and the operating devices in the reverse position from that shown in Fig. 1.

Referring to the drawings, in which like letters of reference denote corresponding parts in both figures, A designates the body or carrying-frame of a dumping-car constructed in accordance with my invention, and B the forward and rear trucks, on which the body is supported, said trucks being of the common pattern and having the usual wheels, b.

Serial No. 280,747. (No model.)

0 D designate the movable tilting recepta cles,which are pivotally mounted on the body or carrying-frame and are adapted to assume both horizontal and vertically-inclined positions, as indicated in Figs. 1 and 2, to respectively carry and discharge the load. Each receptacle has securely fixed to the bottom thereof, at or near the middle, a horizontal transverse beam, 0, which is pivotally connected in any suitable manner, as at d, to a similar beam, d,which is fixed to the carry ing frame or body A of the car.

Depending centrally from the carryingframe A, and immediately below the contiguous ends of the tilting receptacles, is a dis charge-chute, E, which is firmly bolted or otherwise rigidly secured to the frame. This chute E is made flaring, with its larger open end secured to the frame and its reduced end terminating a suitable distance above the surface of the track, to prevent the entire load from escaping from the chute and to permit the same to be uniformly distributed over the track when the car is moved along-the same. This construction and arrangement of the chute or hopper are very useful in repairing railwaytracks; but when it is desired to adapt the car for transporting coal and other commodities theshape and arrangementof the chute or hopper may be Varied aS, for instance, to discharge the load either centrally or laterally, as may be found desirable.

At the ends of the car are arranged lazytongs F and G, the upper members of which are pivotall y connected, as at f, to fixed bracketsf on the under sides of the tilting receptacles at points some distance beyond the pivots of said receptacles. One of the lower members, g, of each lazy-tongs is pivoted, as at g, to a suitable support, 9 fixed to the frame of thecar, and the other lower member, h, of each lazy-tongs is extended or lengthened, as shown, and connected to devices for moving the lazy-tongs.

I is an endwise-movable rod arranged beneath the tilting receptacles, and having one end pivotally connected to the extended member h of the lazy-tongs F at one end of said car, and the other end of'said rod is connected toa piston, j, which is housed in an air-cylinder, J ,arranged at one side of the chute or hopper,

- the opposite direction.

in close proximity thereto, and firmly bolted to the carrying-frame or said hopper. Another endwise movable rod, K, is arranged alongside of the red I, and one end of said rod K is connected with the rod I by an intermediate lever, 70, which lever is pivotally connected to the rods and fulcrumed at one end to the frame A,whereby when the rod I is moved longitudinally the other rod, K, which is coupled thereto, is simultaneously moved in The free or unconfined end of the rod K is pivotally connected to the lower end of the longer member, h, of thelazytongs G.

To relieve the pivots of the receptacles from undue strain, I provide devices for sustaining the approximate ends of the tilting receptacles in an elevated position. These devices may be of any preferred or desired character; but, as shown in the accompanying drawings, these sustaining devices consist of vertical props L, which lie intermediate the frame A and the inner ends of the tilting receptacles. These props can be readily operated to permit the inner ends of the tilting receptacles to drop and assume the reversely-inclined positions indicated in Fig. 2, to discharge their respective loads by gravityinto the central chute or hopper.

To raise the tilting receptacles without exertion on the part of the attendants, one end of a pipe is coupled to the cylinderJ to supply compressed air, steam, or other motive fluid to the cylinder and force the piston j endwise therein to correspondingly move the rods I K simultaneously and cause them to draw on the extended members h of the lazy-tongs F G and simultaneously draw downwardly on the latter and the elevated ends of the tilting receptacles, to cause the receptacles to again assume the horizontal positions indicated in Fig. 1, after which the sustaining devices are readjusted to support the inner ends of the receptacles.

Changes in the form and proportion of parts and details of construction can be made without departing from the spirit or sacrificing the advantages of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a dumping-car, the combination of the tilting receptacles forming the body of the car and independently pivcted to drop or incline at their inner ends, a discharge chute or hopper suspended from the frame of the car, immediately below the inner ends of said receptacles, to receive the loads thereof, a cylinder having a piston, and rods operated by said piston and connected by intermediate devices with said receptacles, substantially as and for' the purpose described.

2. In a dumping-car, the combination of the tilting receptacles pivotall y supported on the frame of the car, the endwise-movable rods, each having an independent connection with the receptacles, and a cylinder having a piston connected with one or both said rods, substantially as and for the purpose described.

3. In a dumping-car, the combination of the tilting receptacles pivotally supported on the frame of the car, the endwise-movable rods, lazy-tongs intermediate the ends of the rods and the tilting receptacles, and mechanism for simultaneously moving said rods, substantially as described.

4-. In a dumpingcar, the combination of the tilting receptacles pivotally supported on the frame of the car, sustaining devices for holding theinner ends of the reccptaclesin elevated positions, the endwise-movable rods coupled together by an intermediate lever, lazy-tongs pivotally connected to each receptacle, and having an extended member, it, connected to the outer end ofoneofthe rods, and a cylinder having a piston therein connected with one of the rods, substantially as described.

5. In a dumping-car, the combination of the tilting receptacles pivotally supported on the frame of the car, devices forsustaining the inner ends of the receptacles inelevated positions, lazy-tongs connected to said receptacles, the endwise movable rods connected to the lazy-tongs and coupled together to move simultaneously in opposite directions, a cylinder having a piston connected to one of the rods, and a common discharge chute or hopper ar ranged immediately below the inner ends of the receptacles, substantially as described.

In testimony whereofI affix my signature in presence of two witnesses.
